Description

A kind of source pump dehumidification control method
Technical field
It is more particularly to a kind of to apply source pump dehumidification control method the present invention relates to humid control field.
Background technology
Humidity is excessive in green house of vegetables, influences whether the normal growth of shed vegetable.Winter temperature is relatively low, is unfavorable for crop Growth, and the generation of vinyl house serves important function to the disparities between supply and demand for alleviating vegetables dull season.But in order to keep greenhouse Interior temperature, vinyl house is usually airtight, and such case easily causes air humidity increase, the normal moisture of plant in canopy Transpiration is suppressed, and the normal water circulation of soil can also slow down, and then induces or aggravate the generation of pest and disease damage, it is also possible to causes to fall Flower shedding and the dew condensation phenomenon on crop blade face.Therefore, it is noted that dehumidifying, to ensure to carry out annual earnings in winter greenhouse greenhouse.
At present, source pump is widely used in the field that warmhouse booth, swimming pool etc. require to indoor temperature and humidity Institute.Traditional source pump dehumidification function can just stop dehumidifying after goal-setting damp condition is reached, if indoor humidity compared with Height, unit can keep dehumidification mode for a long time, and so as to cause indoor circumstance temperature to reduce, and too low indoor circumstance temperature not only influences comfortably Degree, if unit is applied in the environment such as warmhouse booth, will also be adversely affected to the growth of plant.
The content of the invention
In order to solve problem of the prior art, the invention provides a kind of source pump dehumidification control method, saves energy consumption, Extend press service life, ensure that indoor circumstance temperature is stable.The technical scheme is as follows：
